Specification forming part of Letters Patent No. 37,593, dated February '3, 1863..

.Toallwhom it may concern Be it known that I, SAMUEL J. SEELY, of

:Brooklyn, in the county of Kings and State'of New York,'have'inve'nted .a new and useful improvement in machinery, whereby metal sheets can be corrugated very regularly and so as to possess great stiffness and strength;

and I do hereby declare that the following is a full, clear, and exact description of the same,

reference being had to the accompanying drawings, forming partof this specificatiom Figure 1 is a front elevation of my machine. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a horizontal section Fig. 4, view of cam-disk.

Similar letters of reference in the several figures indicate corresponding parts.

A is a strong metal frame with a flat feed ing' and supportingtable, B 0,011 opposite sides. The part B of the table has two dogs, at, the-dog 0 .being' adjustable by meansof a slot, 0, and set-bolt'd. These dogs holddown the sheet of metal while it is being corrugated,

and any' width of sheet is admitted under them by reason of the adjustability of the dog b. Between the parts B O of the table, in. the c'enter'of the frame, two horizontal female dies,

D E,- are screwed firmly "-to. the lower ribbed cross-beam, e, of the frame A. These dies intheir transverse section present a groove configuration resembling the letter V, or the letter U, or other shape that it may be de? sired. to'corrugate the sheet metal.- These dies, by being screwed to the beam 0, are susceptible of being removed atpleasure and sub stituted by others of deeper or 1 shallower grooving. Directly over the dies D E two male dies, F G, shaped to match into the female .dies, are suspended. by means'of vertically-sliding gates or sash-beams H I, fitted to grooves'f on the inner sides of the uprights of the frame A, said-'sash-beams being connected to an adjustable ribbed cross-head, J, of the frame A by means of toggle-levers K K, as represented. The levers Kof thesashbeam H are independent in their. movement of the levers K of the beam I. Each series of levers are connected at their .joint g to a vibrating bar, M,' and therefore the whole series operate simultaneouslyupon thejsash-; beams. i I

The levers are all connected to the sashbeam and to the cross-head J in such a manher that they may'be'rem'ove'd and substituted, by longer or shorter levers. ;So, aeg s-m connection ofthe inale'die's to the sash-beams made-in such manner that the dies may-bere a moved and substituted bydies which arennade" with a deeper corru gatin g ed ge ora' shallower one,as desired. To accommodatethesechanges the cross-head J is fitted to the-"uprights of the-frame A by meansof grooves or slots hk in the uprights and 'by bolts'i '13 of {the cross head, the'bolts passing through thefslot's-a'nd end flanges of the crosshead. and holding the cross-head. in position by. means of their heads binding against-the uprights through theac' tion of nuts on their ends ;"and, asa further support for the cross-head and a means for adjusting it to suitthe changes made in the levers anddies, twoh-and-screws, N N,'are provided, as shown. These screws attach to the top of. the cross-"head near each end and extend up through bracket-nuts'j'j of the uprights of the frame A. By turning the hand-Q wheel nuts 1 l of the screws the adjustment'up' or down may be, eii'ected. V

The-machine thus constructed is opera-ted by means of a cam-wheel, O, which has camgrooves of'the configuration show'nLatQja q'.in

its opposite faces. 1 Both of these grooves are of heart form and of the relative size and arrangementshown inthe' drawings. In the grooves pintles n, o'of'slide-rods r 8 fit loosely,

said rods being connected-to thebars M ofthe toggle-levers by linksG G, as shown, The

disk in which the cam-grooves are cut may have an eccentric-pin and be worked'by a .pitman, or it may have cog teeth on its cir 'cumference and gear with a pinion of a beltshaft, 0, as represented.

Eccentrics might be used in place of the toggle-levers for operatingthe dies, in which case the cams would be dispensedwith and the motions of the eccentrics timed to produce the desired effect.

It is evident from the drawings that the cam p, when in the position shown by 40', causes the toggles to hold the corrugating or main acting die F out of its fellowfemale dieD' ;'also', that at thesam'e time the cam q, when ill' tll6 po-- sition indicated at-y, causes the toggle-levers K to hold the retaining-die G down'in its fellow female die E. It will also be evident that if the cam-disk O is turned in the direction ofq will not operate upon the pintle 0- of the side-rod s, but that the eccentric portion o of the cam 10 will operate upon the pintle 'n of the slide 1', and thereby cause the toggle-1evi rs to assume a straight vertical position and force the die F, 'which corrugates the metal, down into its Ifellow female die D. It also w 11 be evident that the two cams p and q operate between the. points to 'w' and a0 it upon the two pint-les o it simultaneously and in the same manner, and thus cause't-he slides r s to break the joints 9 of the levers and the levers to elevate both dies F G out of theirfellow female diesD E.

From the above operation of the cams it is evidentthat ifthe sheet of metal had been introduced under the corrugating-die before that die was al=lowed to descend, a corrugation would have been formed in it, and now, by putting the sheet of metal farther through the machine, so as to bring the corrugation thus formed directly under the retaining die and into the fellow female dic' thereof, as shown in Fig. 2 by red lines, and'continuing' to turn the disk 0, 'thatiportion of the cam o between w and u will cause the retaining-die G to descend into the corrugation of the metal sheet and hold the same firmly. While this is proceeding the concentric portion of the cam 12 between 71: and a does not act upon the connections of the corrugating-die F, but as soon as the-retaining-die G is downin the corrn gation of the sheet of metal the eccentric portion of the cam 10 between .the points 2: and o causes the corrugating-die to descend upon the plain portion of the metal sheet and to form a corrugation in it. The corrugation descends into the female die as the corrugatingdie depresses the metal of the sheet. While this is proceeding theretaining-die G remains still and firmly holds thev metal .in form and position for the proper action of the corrugating-die. Thus the operation continues until the sheet is finished. v

In the drawings, I have represented the bed or table B O as below the level of the top of the female dies D E, but in practice the part B of the table should be on a level with the top of said dies. The part O is set below to accommodate the corrugations as formed on the steel.

By setting up one end of the crossbeam any desired twist at one end of the sheets may be imparted.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. So operating, retaining, and corrugating dies together in a machine for corrugating.

sheet metal that the retaining-die forms'the first corrugation and takes into the corrugations formed successively by the corrug-atingdie, substantially as and for the purpose set guide-screws, for the purpose set forth.
